How to service and repair the Brake Master Cylinder on GMC Sierra 1500?

You can work on the Brake Master Cylinder's primary Piston by fixing the mounting flange in a bench vise to expose its backside. Put on suitable brake fittings that fit into the master cylinder ports. These fittings should match the necessary flare seat to hold tubing securely. Connect transparent hoses to the fittings of the Brake Master Cylinder and feed them toward the reservoir. Pour delco supreme ii® (GM P/N 12377967) or dot-3 brake fluid from a pure source up to the halfway point of the reservoir while submerging both ends of the hoses inside. Push and release the smooth primary Piston tool several times to a depth of 25 mm using a raw round tip as fluid exits the ports during bleeding. Air removal causes Piston travel to decrease and actions to push forward to increase. Take successive action with the tool until brake fluid emerges without aeration from the port outlets. Reinstall the master cylinder reservoir parts and disconnect the hose fittings from their ports. Then wrap the master cylinder with a clean cloth to prevent spills while taking it out from the vise.

Q: How to service and repair the Brake Master Cylinder on GMC Sierra 1500?
A: You can work on the Brake Master Cylinder's primary Piston by fixing the mounting flange in a bench vise to expose its backside. Put on suitable brake fittings that fit into the master cylinder ports. These fittings should match the necessary flare seat to hold tubing securely. Connect transparent hoses to the fittings of the Brake Master Cylinder and feed them toward the reservoir. Pour delco supreme ii® (GM P/N 12377967) or dot-3 brake fluid from a pure source up to the halfway point of the reservoir while submerging both ends of the hoses inside. Push and release the smooth primary Piston tool several times to a depth of 25 mm using a raw round tip as fluid exits the ports during bleeding. Air removal causes Piston travel to decrease and actions to push forward to increase. Take successive action with the tool until brake fluid emerges without aeration from the port outlets. Reinstall the master cylinder reservoir parts and disconnect the hose fittings from their ports. Then wrap the master cylinder with a clean cloth to prevent spills while taking it out from the vise.
